* btrfs-progs: autoconf: cleanup compilation flags usageKarel Zak2015-01-28
| | | | | | | | | | | | | | | | | | | - define basic default CFLAGS in configure.ac, because: * autoconf default is -g -O2, but btrfs uses -g -O1 * it's better to follow autoconf; standard way to modify CFLAGS is to call: CFLAGS="foo bar" ./configure - move all flags to one place in Makefile.in - don't use AM_CFLAGS, the CFLAGS and STATIC_CFLAGS are enough - don't mix objects and flags in $LIBS, it's more readable to add $(libs) to make rules Signed-off-by: Karel Zak <kzak@redhat.com> Signed-off-by: David Sterba <dsterba@suse.cz>

| | | | | | | | | | | | | - use standard PACKAGE_{NAME,VERSION,STRING,URL,...} autoconf macros rather than homemade BTRFS_BUILD_VERSION - don't #include version.h, now the file is necessary for library API only Note that "btrfs version" returns "btrfs-progs <version>" instead of the original confusing "btrfs <version>".

* btrfs-progs: check: Add --readonly flagHugo Mills2015-01-27
| | | | | | | | | | Particularly during support conversations, people get confused about which options to use with btrfs check. Adding a flag, --readonly, which implies the default read-only behaviour and which conflicts with the read-write operations, should help make the behaviour of the tool clear.

* btrfs-progs: Make option parsing more robust to code modificationsHugo Mills2015-01-27
| | | | | | | | | | | | | | The current approach to option parsing, where long-only options are selected on the basis of their position in the long_options array is fragile and painful to modify if options are to be inserted into the list, rather than appended. Instead, use the last field of struct option to return a value which cannot be a char (and hence a short option), and simply switch on those within the case statement.

* btrfs-progs: drop feature defines from C files, in favour of CFLAGS definesDimitri John Ledkov2015-01-27
| | | | | | | | | | | | | | | | | | | | | | glibc 2.10+ (5+ years old) enables all the desired features: _XOPEN_SOURCE 700, __XOPEN2K8, POSIX_C_SOURCE, DEFAULT_SOURCE; with a single _GNU_SOURCE define in the makefile alone. For portability to other libc implementations (e.g. dietlibc) _XOPEN_SOURCE=700 is also defined. This also resolves Debian bug report filed by Michael Tautschnig - "Inconsistent use of _XOPEN_SOURCE results in conflicting declarations". Whilst I was not able to reproduce the results, the reported fact is that _XOPEN_SOURCE set to 500 in one set of files (e.g. cmds-filesystem.c) generates/defines different struct stat from other files (cmds-replace.c). This patch thus cleans up all feature defines, and sets them at a consistent level.

So layout will be the following: btrfs-progs |-tests |-fsck-tests |-001-SOME-CORRUPT-TYPE |-IMAGE-FOR-CASE1 |-IMAGE-FOR-CASE2 2) Test case image types Only 2 types for test case images. a) btrfs-image dump This one is the simplest case, one only needs to add the image to corresponding dir. b) custom script This one is for all the resting cases which can't fit btrfs-image, like csum error or script can generate the image (this reduces the size obviously and good for review) The old binary dump also belongs to this type, so need to add script to extract them.

| | | | | | | | | | | | | | | | When executing 'btrfs fi show' on unmounted device, even no problem happens, the return value is still 1 not 0. The problem lies in search_umounted_fs_uuids(), where when it finds the given uuid, it should return 1, but later uuid copy overwrites the return value, causing it always return 0 under that case. Fix it by pass found as pointer, and return value only indicates whether anything wrong happens, whether found or not is stored in the new parameter.

| | | | | | | | | | | | | | | | | | The newly introduced search_chunk_tree_for_fs_info() won't count devid 0 in fi_arg->num_devices, which will cause buffer overflow since later get_device_info() will fill di_args with devid. This can be trigger by fstests/btrfs/069 and any operations needs to iterate over all the devices like 'fi show' or 'dev stat' while replacing.

As a result, the `[...]` before the string gets interpreted as "quoted text attributes". In this patch, the sed expression is dropped and asciidoc is configured to recognize `<...>` as a unconstrained quoted string (such that `<attr>s` is correctly emphasized) and to avoid adding quotes in contexts where it is not needed. A remaining problem is that some texts (the one between brackets) do not add the emphasis for `<...>`. While this could be solved by replacing `[` and `]` with `&#91;` and `&#93;` using sed, it introduces formatting problems in btrfs-zero-log(8) because the context is ignored.
